1 *Theinven-'tion relates to. hinges, patlul'frly hinges'ahou'twhich the floorracks'ior gratingsof refrigerator cars and the like finay be raiedwfor cleaning the underlyingiioor.' It isl in-object vof the inventio'nl to p'riville` a hinge that will not provide ar'ece uin which brine orothei `water may collectio-canse ri'stigof the hinge.

It is"a yfurther object toprovidey a hiigeJ-that will prevent removal ofthe oorgiatingwhiilin a horizontal position.

Further objects will 'appear fromlthe following description when read inthey light of the panying dra'wingcsh-owingi ustifative "`'e ments of Lthe invention-and where-in:

Fig. 1 is a plan view of a portion of a refrigerator car equipped with hinges of the invention and showing a portion of the Walls of the car in horizontal section;

Fig. 2 is a detail vertical section on line 2 2 of Fig. 1, showingr the grating raised in dotted lines;

Fig. 3 is a detail vertical section corresponding to a portion of Fig. 2 on an enlarged scale;

Fig. 4 is a horizontal section on line 4-4 of Fig. 3;

Fig. 5 is a detail vertical section on line 5-5 of Fig. 4;

Fig. 6 is a transverse section on line 6-6 of Fig. 4;

Fig. 7 is a section corresponding to Fig. l, showing the hinge of the invention applied to a grating of a diierent form;

Fig. 8 is :a detail section on line 8-8 of Fig. '7 on an enlarged scale;

Fig. 9 is a vertical section on line 9-9 of Fig. 8; and

Fig. 10 is a horizontal section on line |0-I0 of Fig. 8.

As shown in Fig. 1, the device is applied to a grating of what might be called a herringbone type, wherein the slats |-5 are at a slight angle to perpendicular lines drawn across a car, the insulating layer of which is shown at I6.

Between an inner lining I1 and a partition I8 there is provided a space for circulation of air, I 9, which opens at the bottom, as indicated at of Fig. 3, and as is customary with cars of the rcfrigerator type, a Waterproof floor lining is indicated at 2| turned up at the edges as at 22, a base member for liner l1 being shown at 23 and milled to provide a support for the cove 24 of the waterproofing layer 2 I.

In the form of grating shown in Fig. 1, the hinge of the invention is formed of a plate 25 selcured by bolts 26 to a stringer .21 of the door gratofthemed"mankementen@ so v `'y "1, game-ring -in-'eepressiensi-s1 wayne freely nrs charged.

It will be seen that when the grating equipped with hinges of the invention is upon the oor the hinge cannot be separated by vertical movement of the gra-ting which is readily apparent from an inspection of Figs. 3 and 5.

When the grating has been raised to an angle of substantially then the arcuate members 3i| may be lifted past the members 38 which form an outer edge of the depressions 31 and the grating may thus be freely removed without removing any pintle pins, nuts, bolts or cotter pins. The grating therefore cannot readily be removed by a single person which fact is of importance as it is found these structures are often surreptitiously removed while the cars are standing empty and open upon a side-track and, being so removed, are used for fuel.

The for-m of grating shown in Fig. 7, having transverse string-ers 40 instead of the longitudinal stringers shown in Fig. 1, calls for a modication of the hinge such as is shown in Figs. 7 to 10, inclusive. As there shown, the plate 42 for bolting to the Stringer 49 is formed with a rib 43 carrying the pintle projections 44, 45 and the arcuate anges or Wings 46, 41. Plate 48 bolted to the base member 23 carries a member 49 projecting inwardly of the Icar to a vertical portion 50 of said member which bears against the inner partition 18', the member 49 beyond the plate portion 50 being formed with arcuate portions 5| spaced apart at the center as at 52 to provide for drainage in the same manner as already described in reference to depressions 31 in connection with Figs. 3 to 6, inclusive.

The function of the various portions of the hinge of Figs. 7 to 10, inclusive, is the same as a1- ready described in connection with Figs. 3 to 5, inclusive.

at aiiyjertendingweb" Minor changes may be made in the physical embodiments of the invention within the scope of the appended claim without departing from the spirit of the invention.

We claim:

A refrigerator car door grate hinge comprising, in combination: iirst and second bracket members for attachment to the car structure and to the floor grate structure, respectively, said rst member having a rst plate portion for attachment to a vertical wall of said car structure, a first vertically extending web portion carried by said nrst plate portion and extending laterally from said nrst plate portion toward the interior of said car, substantially horizontally extending aligned spaced projections carried by said first web portion, said projections having an arcuate outer surface and comprising a cup-like upwardly open pintle receiving recess having an arcuate pintle supporting surface; said second member having a second plate portion for attachment to said floor grate, a substantially vertically extending second web portion carried by said second plate portion and extending between said spaced projections of said first member, horizontally extending pintle means carried by said second web portion and seated in said pintle receiving recess, said pintle means having an arcuate outer surface. a horizontally extending top web portion attached to the upper portion of said second vertically extending web portion intermediate said second plate portion and said pintle means, said top web portion being positioned at substantially the same level as the upper surface of said floor grate and forming in eifect a continuation of said door grate surface, and a wing portion extending laterally from at least one surface of said second web portion, said wing portion having a radially inner arcuate surface spaced radially outwardly of said arcuate outer surface of said pintle means, said radially inner arcuate surface being adapted to move in an arcuate path adjacent and radially outwardly of the outer surface of at least one of said projections for at least degrees angular rotation of said floor grate structure from a horizontal position when said floor grate is rotated on said pintle means about a horizontal axis.
